Ortho Imagery - As the prime contractor, Bradstreet Consultants, Inc. used the aerial photography flown in one session on April 23-26, 2007, by The Sanborn Map Compay, Inc. of Charlotte, NC who acquired approximately 4,000 photos @ a resolution of 0.5' pixel (similar to 1"=600') with airborne GPS using a Z/I Digital Mapping Aerial Camera. Bradstreet Consultants, Inc. painted and repainted ground targets for photo survey control points (~400) to support full analytical aerotriangulation. The aerotriangulation solution was used to set up each stereopair of photos for orthorectification and DTM compilation. The ortho imagery was rectified from the natural color digial imagery employing a digital terrain model (DTM) collected from the 2007 imagery and supplemented from updating some town's original DTM and some town's from scratch using the imagery in softcopy (digital) stereoplotter in the Kork KDMS and DAT/EM AutoCAD DWG format. |
